To calculate the partial derivative, we can use the chain rule of differentiation.

Let's break down the steps:

Start with the expression (TU - V)² In (W - UV) = In (6).

Take the natural logarithm of both sides to simplify the equation: ln[(TU - V)² In (W - UV)] = ln(6).

Differentiate both sides of the equation with respect to T, using the chain rule.

Apply the chain rule: d/dT [ln[(TU - V)² In (W - UV)]] = d/dT [ln(6)].

Simplify the left-hand side by differentiating each term separately.

Differentiate ln[(TU - V)² In (W - UV)] with respect to T using the chain rule:

d/dT [ln[(TU - V)² In (W - UV)]] = d/dT [(TU - V)² In (W - UV)] * d/dT [(TU - V)² In (W - UV)].

Differentiate ln(6) with respect to T: d/dT [ln(6)] = 0.

Evaluate the partial derivative at (T, U, V, W) = (5, 1, 6, 12).

Now let's calculate the partial derivative step by step:

Partial derivative of (TU - V)² In (W - UV) with respect to T:

d/dT [(TU - V)² In (W - UV)] = 2(TU - V)(U - UV).

Evaluate the partial derivative at (T, U, V, W) = (5, 1, 6, 12):

Standard error (SE) is a measure of the variability of the sample mean estimate, and it is calculated using the sample size and the standard deviation of the population. Smaller SEs result in narrower confidence intervals (CI) while larger SEs result in wider CIs.

Social media (SM) can affect the width of a confidence interval by influencing the sample size and standard deviation. For instance, if the sample size is small, the CI will be wider than if the sample size is large, regardless of SM. However, SM can influence the sample size by providing access to a larger or smaller population.

In addition, SM can affect the standard deviation by introducing bias or error in the data collection process. For example, if a survey is conducted through SM and the responses are voluntary, the sample may not be representative of the population, leading to a larger standard deviation.

In summary, SM can impact the width of a CI by influencing the sample size and standard deviation, but other factors, such as the sampling method and level of precision desired, should also be taken into consideration.

The answers, rounded to the appropriate number of significant figures, are as follows:

(a) 1.088 ×\(10^2\)

(b) 2.132

(c) 1.3331 ×\(10^1\) and

(d) 1.05.

Let's calculate the answers to the given operations using the appropriate number of significant figures.

(a) 8.370×1.3×10

To perform this multiplication, we multiply the decimal numbers and add the exponents of 10:

8.370 × 1.3 × 10 = 10.881 × 10 = 1.0881 × \(10^2\)

Since the original numbers have four significant figures, we round the final answer to four significant figures:

1.088 × \(10^2\)

(b) 4.265/2.0

For division, we divide the decimal numbers:

4.265 ÷ 2.0 = 2.1325

Since both numbers have four significant figures, the answer should be rounded to four significant figures:

2.132

(c) (1.2588×\(10^3\))×(1.06×\(10^-^2\))

To multiply these numbers, we multiply the decimal numbers and add the exponents:

(1.2588 × \(10^3\)) × (1.06 × \(10^-^2\)) = 1.333128 × \(10^1\)

Since the original numbers have five significant figures, we round the final answer to five significant figures:

1.3331 × \(10^1\)

(d) \((1.11)^(^1^/^2^)\)

To calculate the square root, we raise the number to the power of 1/2:

\((1.11)^(^1^/^2^)\)= 1.0524

Since the original number has three significant figures, the answer should be rounded to three significant figures:

1.05

a) Median will be an appropriate measure for the distribution. b) Mean will be an approprate measure for the distribution.

Here we already have the data available to us. From the data, we can clearly see that

Mode < Mean < Median

Hence this is a negatively skewed distribution.

Therefore the appropriate measure of central tendency for this distribution will be the median. The median will tell us the point at which the frequency is divided by 50%.

Hence we can say that the median will a more appropriate measure.

Now if the data has another aspect of sex included, then the frequency column would be divided into separate columns with each gender identity taking up its own column.

Since now this will become multivariate data, the best measure of central tendency will be Mean.

The difference in the measure of central tendency will depend upon how skewed the data for every sex will be. For example, if in a country, men preferred to be educated over women, then the mean for men will be a lot higher than that of women. On the other hand, the EDUC for women will be a lot lower.

                                                x=4

Answer:

Simplifying

3x + -1 = 2x + 5

Reorder the terms:

-1 + 3x = 2x + 5

Reorder the terms:

-1 + 3x = 5 + 2x

Solving

-1 + 3x = 5 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-1 + 3x + -2x = 5 + 2x + -2x

Combine like terms: 3x + -2x = 1x

-1 + 1x = 5 + 2x + -2x

Combine like terms: 2x + -2x = 0

-1 + 1x = 5 + 0

-1 + 1x = 5

Add '1' to each side of the equation.

-1 + 1 + 1x = 5 + 1

Combine like terms: -1 + 1 = 0

0 + 1x = 5 + 1

1x = 5 + 1

Combine like terms: 5 + 1 = 6

1x = 6

Divide each side by '1'.

Answer:

w=31, L=34

Step-by-step explanation:

x+x+(x+3)+(x+3)=130

4x+6=130

4x=124

x= 31

width = 31, length = 34 bc it is 3 cm longer

The length and width of the rectangle are 34 cm and 31 cm.

Given,

A wire 130 cm long is bent into the shape of a rectangle which is 3 cm longer than it is wide.

Find the width and length of the rectangle.

It is given by:

Perimeter = 2 ( length + width )

Area = Length x Width

Find the length of the rectangle.

Length = Width + 3 ______(1)

Since a wire of 130 cm is bent into the shape of a rectangle.

The perimeter of the rectangle = 130 cm

We have,

Perimeter = 2 ( length + width )

130 cm = 2 ( width + 3 + width )

65 = 2width + 3

65 - 3 = 2width

2width = 62

Width = 62 / 2 = 31

Putting Width = 31 in (1)

Length = Width + 3 = 31 + 3 = 34

Thus the length and width of the rectangle are 34 cm and 31 cm.

The induction step holds, and we have shown that \(an = 3^n - 1\) for all n.

To solve the recurrence relation an=3an−1+1;a0=1, we can use the technique of backward substitution.

First, we can find a1 by substituting n=1 into the recurrence relation: a1 = 3a0 + 1 = 3(1) + 1 = 4.

Next, we can find a2 by substituting n=2 into the recurrence relation: a2 = 3a1 + 1 = 3(4) + 1 = 13.

We can continue this process to find a3, a4, and so on:

a3 = 3a2 + 1 = 3(13) + 1 = 40
a4 = 3a3 + 1 = 3(40) + 1 = 121
a5 = 3a4 + 1 = 3(121) + 1 = 364
a6 = 3a5 + 1 = 3(364) + 1 = 1093

So the solution to the recurrence relation an=3an−1+1;a0=1 is:

an = 3an-1 + 1

a0 = 1

a1 = 4

a2 = 13

a3 = 40

a4 = 121

a5 = 364

a6 = 1093

And we can see that the pattern seems to be that \(an = 3^n - 1\). We can prove this by induction.

Base case: when n=0, we have \(a0 = 3^0 - 1 = 0\), which is true.

Induction hypothesis: assume that \(an = 3^n - 1\) for some n.

Induction step: we want to show that\(a(n+1) = 3^(n+1) - 1\).

a(n+1) = 3an + 1 (by the recurrence relation)

=\(3(3^n - 1) + 1\)(by the induction hypothesis)

=\(3^(n+1) - 3 + 1\)

The angles between the edges of the resulting pieces are approximately \($56.1^\circ$ and $42.5^\circ$.\)

We know that the rectangle has sides of length 4 ft and 5.5 ft, so we can use the Pythagorean Theorem to find the length of the diagonal \($BD$\):

\($$ BD^2 = 4^2 + 5.5^2 $$\)

\($$ BD^2 = 16 + 30.25 $$\)

\($$ BD^2 = 46.25 $$\)

\($$ BD = \sqrt{46.25} $$\)

\($$ BD = 6.8 \text{ ft (rounded to one decimal place)} $$\)

Now, we can use the Law of Cosines to find the angle between sides \($AB$\)and \($AD$\) in triangle \($ABD$\):

\($$ \cos(A) = \frac{BD^2 + AB^2 - AD^2}{2 \cdot BD \cdot AB} $$\)

\($$ \cos(A) = \frac{6.8^2 + 4^2 - 5.5^2}{2 \cdot 6.8 \cdot 4} $$\)

\($$ \cos(A) = 0.5471 $$\)

\($$ A = \cos^{-1}(0.5471) $$\)

\($$ A = 56.1^\circ \text{ (rounded to one decimal place)} $$\)

Similarly, we can use the Law of Cosines to find the angle between sides \($BC$\) and \($CD$\) in triangle:

\($$ \cos(B) = \frac{BD^2 + BC^2 - CD^2}{2 \cdot BD \cdot BC} $$\)

\($$ \cos(B) = \frac{6.8^2 + 5.5^2 - 4^2}{2 \cdot 6.8 \cdot 5.5} $$\)

\($$ \cos(B) = 0.7416 $$\)

\($$ B = \cos^{-1}(0.7416) $$\)

\($$ B = 42.5^\circ \text{ (rounded to one decimal place)} $$\)

The relationship between the x and y-values and not just the differences in the y-values. A linear function will have a constant rate of change, but a constant rate of change does not guarantee linearity.

Willis made a mistake in his reasoning by assuming that a function with a constant rate of change is necessarily linear. While it is true that linear functions have a constant rate of change, the converse is not always true. In other words, just because a function has a constant rate of change does not mean it is linear.

In this case, Willis calculated the differences in the y-values and observed that they were increasing by 4 each time: 6, 10, and 14. He incorrectly concluded that since these differences were increasing by a constant amount, the function must have a constant rate of change and therefore be linear. However, this is not a valid assumption.

There are non-linear functions that can exhibit a constant difference in their y-values. For example, a quadratic function such as y = x^2 will have a constant difference in its y-values for consecutive x-values, but it is not a linear function.To determine if a function is linear or non-linear, it is necessary to examine

By expressing the complex number (-1+3) as r(cos i + i sin i), where r is the modulus and i is the complex number's argument, we may use De Moivre's Theorem to determine (-1+3)3.

First, we use the formula r = \(((-1)2 + ((-3)2) = 2\) to determine the modulus of (-1+3).

Next, we use the formula = arctan(3/(-1)) = -/3 to determine the argument.

We can now raise the complex integer to the power of 3 using De Moivre's Theorem: (r(cos + i sin))3 is equal to \([2(cos(-/3) + i sin(-/3)]³\).

We get \([23(cos(-) + i sin(-))] = 8(cos(-) + i sin(-)\) after expanding and simplifying.

The degree measure of angle WUB is determined as 20⁰.

The value of angle WUB is calculated by applying intersecting chord theorem as follows;

If line BU is a bisector angle ABC, then angle CBU is calculated as;

angle CBU = ¹/₂ x m∠ABC

angle CBU = ¹/₂ x 40⁰ = 20⁰

The value of arc CU is calculated as follows;

arc CU = 2 x m∠CBU (intersecting secants on the interior)

arc CU = 2 x 20⁰ = 40⁰

Draw a line to join point C and U, then we will have;

m∠ACU = OAC (alternate angles are equal)

OAC = 90 - m∠ACB (complementary angles of a right triangle)

OAC = 90 - 40

OAC = 50⁰

so, m∠ACU = 50⁰

The value of arc BC is calculated as follows;

arc BC = 2 x m∠ACU (intersecting secants on the interior)

arc BC = 2 x 50⁰ = 100⁰

Since line WU is diameter of the circle, arc WAU is calculated as;

arc WAU = 180⁰ (sum of angles in a semi circle)

arc WB = 360 - (180 + 40 + 100)

arc WB = 360 - 320

arc WB = 40⁰
